Distal surface caries in the mandibular second molar is a common outcome of impaction of the adjacent third molar. To determine the prevalence of this type of caries in the Netherlands, 250 radiographs were evaluated. The prevalence among the research population was 26%. Risk factors for developing distal surface caries in the mandibular second molar were partially erupted/impacted third molars with a mesioangular or horizontal angulation, an LD loss of ≥ 2mm and an increased modified DMFT score. The relation between the point of contact of the third molar and the adjacent mandibular second molar, on the one hand, and, on the other, the cemento-enamel junction of the mandibular second molar and the prevalence of distal surface caries almost reached statistical significance (p = 0.052). The relatively low prevalence of distal surface caries in the Netherlands is probably related to the current clinical guidelines recommending early extraction of partially erupted/impacted third molars, particularly in cases of third molars with a mesioangular or horizontal angulation.

In January 2021, the guideline 'Periodontal screening, diagnosis, and treatment in general practice' was introduced as a successor to the so-called paro protocol. Simultaneously, the Dutch Periodontal Screening Index was replaced by the Periodic Periodontal Screening. The experiences of general dental practitioners and dental hygienists with the new guideline were evaluated in the autumn of 2022. Random groups of 1,000 general dental practitioners and 400 dental hygienists were invited to answer an online questionnaire on this topic: 125 (12.5%) general dental practitioners and 102 (25.5%) dental hygienists responded. By the end of 2022, a large majority of both groups were using the Periodic Periodontal Screening. Both professional groups were satisfied with the new guideline. Dental hygienists used the Periodic Periodontal Screening in more cases than general dental practitioners and were also more frequently satisfied with the new guideline. Both oral healthcare professionals believed that the Periodic Periodontal Screening offers better opportunities to involve the patient in periodontal care compared to the Dutch Periodontal Screening Index.

Obstructive sleep apnea is a common sleep-related breathing disorder. Although maxillomandibular advancement is widely recognized for its proven effectiveness, there are still uncertainties surrounding this procedure. This research therefore focused on the indication, surgical techniques, and outcomes of maxillomandibular advancement in patients with obstructive sleep apnea. A systematic review and meta-analysis showed that maxillomandibular advancement is more effective than multilevel surgery for the treatment of obstructive sleep apnea. Both maxillomandibular advancement and hypoglossal nerve stimulation were identified as effective and safe treatment methods for obstructive sleep apnea. Various retrospective studies also indicated that patients with hypopnea-dominant obstructive sleep apnea are better candidates for maxillomandibular advancement, in contrast to patients with cardiovascular diseases or a higher central apnea index. Furthermore, it was demonstrated that maxillomandibular advancement is effective in patients with a high percentage of central and mixed apneas, despite the potential surgical inaccuracies of maxillomandibular advancement, highlighting the broad applicability of this treatment method.

A 45-year-old woman continued to suffer from an open bite, pain in the left temporomandibular joint, jaw muscle tightness, and ringing in both ears 6 months after an unilateral left condylectomy. A recovery surgery was planned to treat the open bite and she was referred to the department for Orofacial Pain and Dysfunction for treatment of the pain complaints, muscle tightness, and ringing in the ears. At this department she was diagnosed with temporomandibular disorders. Muscle tension, oral behaviors, and anxiety were expected to play a role in the etiology. Fear for the recovery surgery contributed to the onset and maintenance of the complaints. A multidisciplinary treatment was started, including counseling, exercise therapy, psychological treatment, and stabilization splint therapy that would take place after the replacement of the temporomandibular joint. After completion of the treatment, the anxiety had disappeared, and the pain and muscle tension were reduced significantly. The remaining pain and muscle tension resolved following a successful recovery surgery and further orofacial physiotherapy.

A healthy, 49-year-old healthy woman presented at a maxillofacial surgery department with pain and a burning sensations in the mouth. She had experienced the discomfort for a year and it had made eating difficult. Clinical examination revealed white, plaque-like lesions on the buccal mucosa and tongue that could not be scraped off. A biopsy was taken by another health professional and oral lichen planus was diagnosed; treatment with triamcinolone dental paste and later clobetasol mouthwash followed. Neither treatment was sufficiently effective. A new biopsy confirmed a diagnosis of oral lichen sclerosus. Lichen sclerosus is a mucocutaneous condition commonly affecting the anogenital region, while the oral variant presents as white plaque. The differential diagnoses consisted of oral lichen planus, oral manifestations of systemic sclerosus (scleroderma) and leukoplakia. When other kinds of corticosteroid therapy are insufficiently effective, an intralesional injection of triamcinolone acetonide might be considered, which proved to be effective in this case.

The development of minimally invasive caries treatment has dramatically changed dentistry. Instead of traditional, often invasive methods that resulted in significant loss of healthy dental tissue, this approach focuses on preserving the vitality of the pulp and minimizing tissue loss by delaying and scaling back restorative treatments. This involves the use of modern methods, with selective caries removal with or without indirect (pulp) capping being the norm for treating extensive lesions. The philosophy of minimal intervention goes beyond treatment choices to include a holistic approach from diagnosis to follow-up care, emphasizing personalized care based on risk profiles. This paradigm shift has greatly improved the standard of care, but continued attention to the risks of overdiagnosis and overtreatment is necessary to ensure optimal oral health.

A 39-year-old woman with severe periodontal inflammation was referred to a periodontist in 2013. Intraoral examination and additional diagnostics revealed generalized periodontitis, stage IV, grade C, with the presence of Aggregatibacter actinomycetemcomitans in the subgingival plaque, according to current classification. Treatment and treatment outcomes are described, followed by consideration of the treatment decisions in light of minimally invasive care and current treatment guidelines.

In recent decades, oral healthcare has shifted from curation to prevention. Preventive oral healthcare for children consists mainly of oral health education to improve health behaviors and clinical prevention such as fissure sealants, application of fluoride varnish, removal of supragingival plaque and dental polishing. In addition, the periodic clinical examination is an important preventive instrument. These 5 preventive interventions for children up to 12 years of age can be discussed using the principles of 'appropriate care'. Appropriate care is an approach of the Dutch government to ensure the accessibility, quality and affordability of care in the Netherlands. Central to the approach are the effectiveness, efficiency and patient-centeredness of care. This article describes to what extent preventive oral healthcare meets these principles based on literature, care consumption data and recommendations from the clinical guidelines 'Oral care for children: prevention and treatment of dental caries' and the 'Advice on Caries Prevention' by the Ivory Cross, a Dutch scientific association for oral health. Appropriate oral healthcare is best served by care that is tailored to both the individual oral disease burden of the patient and their risk of disease as well as to the wishes of the patient.

In cases of agenesis of the mandibular second premolar, a choice can be made from among several treatment options. Besides preserving the second primary molar, it can be decided to close the diastema orthodontically, following extraction of the primary molar. This can be done in several ways: full or partial (hemisection) removal of the primary molar. The procedure for a hemisection initially consists of removing only the distal part of the relevant primary molar, in order to preserve the breadth of the alveolar process and to enable spontaneous mesialization of the first permanent molar. Secondly, the mesial part of the primary molar is removed.

Root canal treatment has been shown to be a predictable procedure with a favourable outcome in the case of pulpitis and apical periodontitis. The most important outcome measure is retention of an asymptomatic and functional tooth. When teeth are lost after root canal treatment, this is often the result of fracture due to weakening. By preventing or postponing root canal treatment, the long-term prognosis of the tooth may be better. Minimal interventions in endodontics are vital pulp therapy (indirect pulp therapy and pulpotomy), postponing and monitoring, and partial revision.
